SMART (missile)
SMART (supersonic missile assisted release of torpedo) is a canister-based, long-range supersonic anti-submarine missile developed by the Defence Research and Development Organisation (DRDO) for the Indian Navy. Description SMART is a canisterised hybrid system, made up of a long-range missile carrier that can travel at supersonic speed and a lightweight torpedo as payload, for anti-submarine warfare (ASW) role. The objective behind the project was to develop a quick-reaction system that can launch torpedoes from standoff distance. The missile has a range of 643 km (400 mi) carrying a light weight torpedo of range 20 km (12.5 mi) with 50 kg high explosive warhead. SMART uses two-way data link connected to airborne or ship based submarine detection and identification systems. SMART can be launched from a surface ship or a truck-based coastal battery. The missile delivery system was developed jointly by Defence Research Development Laboratory (DRDL) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Test Range
The Integrated Test Range (ITR) is a Test and Evaluation (T&E) centre of the Defence Research and Development Organisation (DRDO). Located in Balasore, Odisha, it provide safe and reliable launch facilities for performance evaluation of rockets, missiles and air-borne weapon system. The present director of ITR is Sri. H K Ratha. History As of April 2024, DRDO is working to establish a missile test range at Junput area in West Bengal. The location is 177 km from Kolkata, 40 km from Digha and 70 km from Chandipur. The Range will cover an area of 8.73 acres. The project received approval from Ministry of Environment, Forest and Climate Change. On 10 October 2024, the Cabinet Committee on Security approved the proposal for the establishment of a new missile testing range in Nagayalanka region in Andhra Pradesh. This will likely be the revival of the Machilipatnam Test Range Project. On 25 February 2025, DRDO and Indian Navy The Indian Navy (IN) (ISO 15919, ISO: ) is the Nav ...

Supersonic Speed
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach number, Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inertial Navigation System
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors (magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Design Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object ...

Actuator
An actuator is a machine element, component of a machine that produces force, torque, or Displacement (geometry), displacement, when an electrical, Pneumatics, pneumatic or Hydraulic fluid, hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. An actuator translates such an input signal into the required form of mechanical energy. It is a type of transducer. In simple terms, it is a "mover". An actuator requires a control device (which provides control signal) and a source of energy. The control signal is relatively low in energy and may be voltage, electric current, Compressed air, pneumatic, or hydraulic fluid pressure, or even human power. In the electric, hydraulic, and pneumatic sense, it is a form of automation, automation or automatic control. The displacement achieved is commonly linear or rotational, as exemplified by linear motors and rotary motors, respectively. Rotary motion is more natural for s ...

Solid-propellant Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/ oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder. The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in facilitating their westward adoption. All rockets used some form of solid or powdered propellant until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Because of their simplicity and reliability, solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications. Since solid-fuel rockets can remain in storage for an extended period without much propellant degradation, and since they almost always launch reliably, they have been frequently used in military applications such as missiles. The lower performance of solid propellant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Underwater Thruster
An underwater thruster is a configuration of marine propellers and hydraulic or electric motor built into or mounted to an underwater robot as a propulsion device. These give the robot movement and maneuverability against sea water resistance. The main difference between underwater thrusters and marine thrusters is the ability to work under heavy water pressure, sometime up to full ocean depth. Types of underwater thrusters There are three general types of thrust devices: the lateral thruster or tunnel thruster, which consists of a propeller installed in a athwartship tunnel; a jet thruster which consists of a pump taking suction from the keel and discharge to either side; and azimuthal thruster, which can be rotated through 360° Underwater thrusters can be further divided in two main groups, hydraulic thrusters and electric thrusters. Below are some pros and cons of each type: Hydraulic Thrusters Hydraulic thrusters are mainly used on larger work class ROVs, mainly bec ...

Defence Research And Development Laboratory
Defence Research and Development Laboratory (DRDL) is an Indian missile development laboratory, part of the Defence Research and Development Organization (DRDO). Their charter is centered on the design, development, and flight evaluation of various types of missile systems for the Indian armed forces. History In 1958, the Indian government constituted a team of engineers, mostly from the Indian Ordnance Factories Service - called the Special Weapons Development Team - to research guided missile weapons development. It was founded by S. P. Chakravarti, the father of Electronics and Telecommunication engineering in India, who also founded the DLRL and the Electronics and Radar Development Establishment (LRDE). This team was later expanded into DRDL, a full-fledged laboratory, in June 1961, at the campus of Defence Science Centre, Delhi. It later shifted to Hyderabad after the state government granted them the former Nizam's army barracks. This was the genesis of the Defence ...
